Averett realized the laptop wasn’t in his knapsack after he boarded his plane, and initially thought he had let it in a plastic scanning bin.

However, Rosario was seen on surveillance video taking the laptop and admitted to the theft when a TSA supervisor confronted him about it at his Bronx apartment, cops said. He is due back in court on Jan. 31

“I’m just relieved I didn’t have to buy another one,” said Averett, who had school documents saved on the laptop.

Rosario is no longer employed by the TSA , said an agency spokeswoman.
